(1) Paper fed from 1st Tray
1. As illustrated in Figure 2-1, when the solenoid is ON, the register motor rotates
(Counterclockwise turn), transporting the paper until the IN1 sensor comes ON. (When the
solenoid is ON, the paper feed roller is driven.)
2. After causing the IN1 sensor to come ON, the paper is further carried over a certain distance
to finally hit register roller L. (This corrects skew of the paper.)
3. As shown in Figure 2-2, the solenoid is turned OFF and the paper is transported by register
roller L. (When the solenoid is OFF, register roller L is driven.)

(2) Paper fed from MPT
1. As illustrated in Figure 2-3, when the solenoid is OFF, the register motor rotates (Clockwise
turn), transporting the paper until the IN2 sensor comes ON. (As the register motor rotates
clockwise, the MPT paper feed roller is driven.)
2. After causing the IN2 sensor to come ON, the paper is further carried over a certain distance
to finally hit register roller U. (This corrects skew of the paper.)
3. As shown in Figure 2-4, the register motor rotates (Counterclockwise turn) to let register
roller U transport the paper. (As the register motor rotates counterclockwise, register roller
U is driven.)
